我正在使用jQuery Fileupload上传文件.它不发送我设置到服务器的标头.为什么Authorization标头仅在IE中缺失但在chrome中传递？

这是代码:

upload_photo: function(){
  var url =  '/api/v1/upload';
  $('#photoupload').fileupload({
      url: url,
      dataType: 'json',
      paramName: 'uploadFile',
      beforeSend: function ( xhr ) {
          setHeader(xhr);
          $("#check_progress").html('true');
      },                    
      done: function (e, responseJSON) {
          var id = responseJSON.result.id;
          url = responseJSON.result.url;
          var photo_ids = $("#photo_ids");
          var val = photo_ids.val();
          photo_ids.val(val + id.toString() + ",");
          $(".photothumb-wapper").append('<div class=\"photothumb\" id="post_photo_'+id+'"><div><img  src=\"'+url+'\" /></div><img class=\"thumb-delete photo_delete\" id=\"'+id+'\" title=\"Remove\" src=\"/assets/delete-red.png\"></div>');
          $("#check_progress").html("");
      },
      start: function (e, data) {
          $(".photothumb-wapper").append('<div class="photothumb photoprogress" style="border:none"><img src="/assets/ajax-loader.gif" /></div>');
      }, …

这就是我在Ruby中所做的.

time = Time.now
=> 2013-10-08 12:32:50 +0530
time.to_i //converts time to integer
=> 1381215770
Time.at(time.to_i) //converts integer to time
=> 2013-10-08 12:32:50 +0530

我正在尝试使用Node.js实现相同的功能,但不知道该怎么做.请帮我找到一个用Node.js,Javascript实现相同的模块.谢谢!

是否可以在Controller中存储用户的Cookie或会话,并通过从JS或Jquery访问cookie来获取cookie？

我从Rails 3.0.11升级到3.1.3.当我启动服务器时,它给出了错误:

我能够test_case.t为Perl模块编写单元测试ModuleOne.pm

test_case.t

use strict;
use warnings;
use Test::More;
use Test::Cmd;
use ModuleOne; # Included the module here

my $ret = ModuleOne::methodone(args);
is($ret->{val}, 1, "Checking return value"); # success 

我正在尝试为Perl脚本实现相同的单元测试用例 script_one.pl

script_one.pl

use strict;
use warnings;
use ModuleOne;

my $NAME;
my $ID;

# get parameters
GetOptions (
 "name" => \$NAME,
 "emp_id" => \$ID,
)

validate_params();

sub validate_params {
   # this method will validate params 
}

sub print_name {
   # this method will print name 
}

我如何script_one.pl在这个Perl文件中包含 …

这是我的代码：start_end.js

var glb_obj, test={};
var timer = 10;

test.start_pool = function(cb) {
   timer--;
   if(timer < 1) {
     glb_obj = {"close": true}; // setting object
     cb(null, "hello world");    
   } else {
     start_pool(cb);
   }
}

test.end_pool = function(){
  if(glb_obj && glb_obj.close) {
    console.log("closed");
  }
}

module.exports = test;

测试用例：

var sinon = require('sinon');
var start_end = require('./start_end');

describe("start_end", function(){ 
   before(function () {
      cb_spy = sinon.spy();
   });

   afterEach(function () {
    cb_spy.reset();
   });

  it("start_pool()", function(done){
     // how to make timer variable < 1, so …

我可以在database.yml中设置的最大池大小是多少？我正在使用Mysql Db.

我有20个独角兽进程在24核,32GB RAM机器上运行.

我想换"@"到"\40"一个字符串.但我不能这样做.

a = "srikanth@in.com"
a.gsub("@", "\40")
# => "srikanth in.com"

它\40随着空间而变化.知道如何实现这个吗？
